K tomu Avivo bych dodal asi jen tohle
This is different from ATI's Avivo technology, which decodes H.264 video on Radeon X1000 series cards. Avivo uses pixel shaders to decode the video, and this places a limitation on what cards can handle what resolutions. The X1300 can handle 480p H.264 video, the X1600 can handle 720p and the X1800 can handle 1080p.
In contrast, the integrated graphics chipset GeForce 6150 can handle 720p, whilst 6600GT, 6800, 7600 and 7800 cards can all do 1080p.
